Thank you for your response, it is very strange because I can navigate in HTTPS the website and also the webapi with IE or Chrome without having any errors about the SSL; if I click the lock into the navigation bar of the browsers they say that the website is secure and the certificate will expire in 2022; and more, the same remote endpoint works perfect from my workstation; is there a way to disable every control of the SSL certificate in Internet Options or in DataFlex?
